JOSEPH KAYSER, OF NEW YORK, N. Y.

AUTOMATIC WATER-GAGE VALVE.

SPECIFICATION forming part of Letters Patent No. 365,475, dated June 28, 1887.

Application filed February 3, 1886. Serial No. 190,685. (No model.)

To'aZZ whom it may concern.-

Be it known that I, J OSEPH KAY'sER, of the city, county, and-State. of New York, have invented a new and useful Improvement in Automatic Water-Gage Valves, of which the following is a full, true, and exact description, reference bcinghad to the accompanying drawings.

said valve may be operated independent of my new automatic valve, while at the same time said valve will serve to open my automatic valve when a new glass has been inserted.

My invention will be readily understood from the accompanying drawings, in which- Figure 1 represents ageneral view of a glass water-gage with my improvement applied 5 Fig. 2, the details of the construction.

A represents the valve-box; B, the ordinary screw-stem, the inner end of which is provided with a conical valve, F. A conical check-Valve; E, seats against the seat K, as shown. This valve is normally held away from its seat by the light spring 0. A pin, D, attached to the stem B, passes through the center of the spring 0 and abuts against a suitable portion of the valve E. The stem B is operated by a handle and screw-thread, G, in the usual way.

The operation of the valve can now be readily understood. Normally the check-valve E is in the position shown in Fig. 2, suitable slot-s being provided, as shown, to allow the passage of the steam or water past it. The stem B being withdrawn, water will flow freely into the glasstube H. If at any time the glass tube should break while a pressure was on the boiler, the check-valves E at the upper and lower ends would instantly close, and thereby prevent any further escape. A new glass can then be inserted; and when this is done, by simply screwing. in the handles, the checkvalves will be moved away from their seats and come under the action of the spring again, and by again opening the valves F water will resume its place within the tube.

Vhat Iyclaim as my invention, and desire to secure by Letters Patent, is

1. The combination of the automatic checlu valve E, the valve F, the pin D, and the spring 0, whereby the closing of the valve F automatically opens the valve E, while the opening of the valve F does not close the valve E, substantially as described.

2. In an automatic gage-cock, the combination of the valve E and its seat F with the screw-stem B, having the pin D, and the spring 0, surrounding the pin D and bearing against the outer portion of the valve E, substantially as described.

In testimony whereof Ihave signed my name to this specification in the presence of two subscribing witnesses.

JOSEPH KAYSER.
